Solution

The correct option is A edbac
The correct sequence of operations is:
(i) Taking equal masses of fine granules of zinc in two test tubes A and B.
(ii) Addition of same concentration of $H C l$ to the two test tubes.
(iii) Heating the test tube by $10^{o}$ C.
(iv) Measuring the volumes of $H_{2}$ gas liberated in the two test tubes.
(v) Comparison of relative volumes of $H_{2}$ liberated in test tube B and A.
